What is Music Fingerprinting?
"A digital music identification system that can search through 17 million songs in under 1 second has been launched in the US. MusicIP, based in California, US, announced last week that it had received a US patent for its method of automatically identifying, or 'fingerprinting,' digital music files. The company already offers software that analyses the music collection on a computer, identifies it, and makes recommendations. But now it will offer its music identification feature for other companies to include in their products." MusicIP offers several free tools including the MusicIP Mixer (free) application and this web-based database.
